1. Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape (175 parts per full
reel). Quantities less than full reel available: in tape (not machine ready) or
with leader and trailer ($25 charge).
2. Inductance is for the primary, measured at 200 kHz, 0.2 Vrms, 0 Adc.
3. Minimum inductance for the primary, measured at 200 kHz, 0.2 Vrms, 2 Adc.
4. Leakage inductance is for the primary, measured with secondary windings shorted together.
5. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
